ok .. I'm with a doubt, how do I get when I download new updates from SVN for example l2jserver ... I do not need to replace the config of my server for example, I edited the. sieges.propriets  ... If they update some line and I do not lose my changes?

Check if there is something new in it, than write it again, or copy and paste what you have done :)

ok, and SQL. execute tools database_installer and upgrade my tables? allright?

dont use the upgrade part of the installer sometimes its work unproperly also if you modify it in your pc without using your own svn theres a better and faster way add your own patch than if you want to sync it to the latest version use the update fucktion of eclipse and than correct the conflicts
